To all whom it may concern: 7

Be it known that I, BENJAMIN WoLHAUP- TER, a citizen of the UnitedStates, residing at New York city, in the county of -'New York and StateotNewYol-k, have invented certain new and useful Improvements inInsulated Rail-Joints, of which the following such a disposition of theinsulation that there is no insulating material which is required tocarry the load or weight of the passing trains. i

To this end the invention primarily contemplates an improvement in theconstruction of the joint bars whereby the latter shall be moreeffectively reinforced at'the weak pointof the joint, thatis, at a pointgenerally im rove the reinforcing and stiffen'-' between the ties uponwhich the joint is supported. I

A further object in this connection is to ing of the jolnt barsthroughout their entire length, while attthe same time preserving thefeature of providing each joint bar along one end portion with ashortlength base section affording one rail end the' support ofthe ties onboth sides'of the meeting point of the rails without contact with thecorres onding base section.

Wit these and many other objects'in view, which will more readily appearas the nature of the invention is better understood, the same consistsin the novel construction, combination, and arrangement of parts,hereinafter morefully described, illustrated, and claimed.

The essential feature of the invention above indicated is susceptibleto'embodiment in a variety of forms of joints, particularly of the typesdisclosed in my companion applications, to-wit:'filed November 8,

Like references designate corresponding- As indicated, the presentinvention is specially applicable to those types of insulated railjoints embodying a two art or seetional supporting base for the raiends,aand

wherein each sidejoint bar is provided along one end portion Wlth ashortlength base section aiiording a supp ort for one rail end,

Hence, the various forms of-insulated rail joints involving said baseconstruction. may

be provided wlth the special reinforcement claimed herein. -.Thisreinforcement may likewise be associated with side joint bars ofvariousv designs, yi'rrespective of Whether .95? these joint barsconstitute the upright memf-' bers of .joint shoesgor shoeangles, or arein the form of' angles or s lice bars arranged-i over the railbases,"andlsposed beneath therail heads.

' Referring to thesfiocific exemplifications of the invention showntihthe drawings, Figs. V 1, 2, and 3 of the latter.- illustrate aninsulated joint comprising in its organization the serv-- ice rails1"and'2, the ifippc'isit side joint bars 3 and 4,.the wooden 4 j betweenthe side joint bars and the si es'of er blocks 5 inte osed' therails,and" the usual series of joint bolts 6. Inthis joint, the sidejoint" bars 3'Iand4" are shown asconstituting the upright meni- I10provided along one end portion thereof with a-"s hort length basesection6 aflording one rail end the support of the ties'on both sides ofthemeeting point of the rails. 1 and 2 without contact with thecorresponding base sec tinguis'hing eature in the design and construction' of the side joint bars in the resent tion of the other jointbar. In this particular, the joint bars 3 and4' are of the same designand subserve the same functions as the corresponding members disclosedin my companion afpplication's aforesaid, but a disinventionresides'inproviding each si e joint bar along its'bottom edge with anintegral offstanding foot 7 constituting a reinforcing and spikingflange, and also with a centrally arranged depending reinforcing girder8.

' The reinforcing girder '8 which depends from 20" the bottom edge ofeach side "oint bar occuies'a position intermediate t e ends of the bar,and henceat themiddle of the joint in the transverse plane of themeeting ends of the rails, thereby disposing the said girder at a pointbetween the two ties upon which the jomtis supported. This dispositionof the depending reinforcing. girder '8, in conjunc tion, withtheofl'st'anding foot or reinforcing flange 7, provides a materialstiffening and strengthening of the joint her not only through itsentire'extent, but also at a point where most needed, at the middle ofthe joint.

The centrally arranged depending. girder 8 of each'joint bar ma beformed in various ways on the bar, in t e process of manufacturing thelatter, and in the construction suggested in Figs. 1, 2, and 3,'it willbe observed that the said girder 8 may be rolled as a part of the footor flange- 7 and severed from thelatter along the lines of cut desigivnated by the reference number 9 in Fig. lot

the drawings, thereby-permitting the sections of the foot or flange 7 tobe bent to the' relative positions shown in the drawings.

In the joint shown in Figs. 1, 2, and 3 of the drawings, -any suitableinsulating expedie'nts may be utilized to complete the insulationthereof, such for instance as. the insulating end post 10 between therail ends,

the insulating strips 11 between each basesection 6- and-the oppositejoint bar, and the insulatin sleeves or bushings 12 arranged in the be tholes in the'rail websand receiv in the joint bolts therethrough." Thesein-- su atingfeatures, however, may be varied" without in any wayafiecting the presentmvention'. 1

Another modification of the invention is shown in Fig. 4 ofthe drawingsillustrating an Insulated j oint comprising the service rails 1 l and 2,the opposite side joint bars 13 and ocks 15 interposed between thejointbolts 16. "This joint also includes ave here of shoeangles, andeach of the same is gin its construction the feature of providing eachside joint bar along one end portion thereof with a base sectlon 17affording a support for one rail end and maintaining the same relationto the base section of the opposite side joint bar asillustrated in Fig.3 of the drawings. Also, the joint shown in Fig. 4- includes the detailsof suitable insulation 18 between the rail ends, and insulation 19between each basesection and the opposi side joint bar, and it will befurther 0 serve that, in thedesign of joint described, the side jointbars 13 and 14 are illustrated as being set at an angle to a verticalplane and binding against correspondi'ngly inclined bearing faces 20 onthe outer sides of the wooden filler blocks I 15. In connection withthis ing eac side joint bar at its bottom edge with an oflstandingreinforcing and spiking foot flange 21' and having the central orintermediate portion of this flange bent downwardly, as at 22, toprovide an'intermediate depending reinforcing girder occup ying aposition. between the ties in the transverse plane of the joint betwetsnthe'nieeting ends of the rails, thus eflecti g a strong remforcing ofthe joint bars at the middle of the joint. In connection with theconstrucconstruction of joint, the presentinvention conte1n hates thepractical feature of providtion described, it'will be further observedthat the form of the foot flange 21 provides outstanding reinforcingwebs or ribs 23 at the end edges ofthe girder 22' forming directintegral continuations of the main dportions of the foot flange 21. Thissame esign of reinforcement, such as shown in Fig. 4:, is .illustratedin Fig. 5as applied to an angle bar type of insulated rail joint.'Ileferring to the latter, the same includes the service rails 1 and 2,the side joint bars- 24 and 25, and the serieslof joint bolts 26. Also,in this design of joint, each of the side joint bars is rovided alongone end portion thereof wit an integral short length base section 27affording a support for onerail end and occupying the same relation tothe base section of the o posite side joint bar as-shown in Fig. 3 o thedrawings. Furthermore, the special design of joint shown in Fig. 5includes the details of suitable insulation 28 between the meeting endsof the rails, side insulating sheets 29 between the side joint bars andthe rail sides,

- and suitable insulation 30 for the joint bolts.

A distinctive characteristic of the joint shown in Fig. 5.resides in thefact that the side joint bars 24 and 25 are in the form ofcontinuous'angle bars fitting over the rail I bases and into the sidesof the rails beneaththe heads thereof. Each of said side joint bars 24and'25 (of the angle bar -ty is rovided at its bottom edge with the ostan ing reinforcing and spiking foot flange 31 lia'ving bent downwardlytherefrom the centrally 10- cated depending reinforcing girder 32 andthe outstanding reinforcing webs.ortibs-33..said depending bottomflange, the end portions of members 31 ,'32, and '33 being of the same.which latter are shearedoff to leave the cendesign and arrangem 'ntandsubservingrthe "trall'y arranged de ending girder 37.
